Inherited retinal diseases (IRDs) are a group of genetic degenerative disorders of the retina and affect more than 200 million people worldwide. Mutations in genes that are responsible for retinal function can lead to visual impairment and, in some cases, blindness. IRDs are inherited in autosomal dominant, autosomal recessive, mitochondrial, or X-linked patterns with varying penetrance, resulting in a highly variable clinical course.
In the clinical setting, a variety of symptoms may suggest an inherited retinal disease, particularly when the symptoms cannot be explained by other diseases. A detailed medical history including family pedigree, functional limitations, and medication history can support an initial suspicion of IRD and may guide further examinations. The genetic heterogeneity of IRD makes diagnosis challenging; however, patients who receive a definitive diagnosis are better able to prepare for the interpersonal, social, and occupational impacts of their disease.
